Another item with filezilla is it prompts you for the same identical files that exist on the site so make sure you select to overwrite them for the same queue at the very least or select the always option.

I used wsftp for years with classic with no problems.
When I upgraded to threads it caused the same problem you have due to it would write a extra file"log.txt" to all of the folders.

So sometimes you need to step back from the monitor take a moment and double check even the most simple tasks that seemed to always work before.

Just a thought ehm1.
Since Rick identified most of the problem now is with the Portuquese language file. Your working copy may be corrupted.
Since you created it to begin with in the language pack forum. Maybe you need to download your own zip file you posted and start over.
It seems to be okay at this site.

It might save you some time???

Thanks, but I changed the language profile of one TestUser and the problem still.
I'm assume there is something wrong on the line Rick is telling me, but I can't find where else.
I already checked every single file on the Portuguese language, since the other ones I just download from the Install Pack.

I responded to your ticket again. It should be working now. Your libs/captcha.inc.php had the blank lines problem which I fixed.

Okay I use v7.5.3 I just installed your language pack made it the default. Logged off. When I attempt to register the captcha works fine it even refreshes with a new display.
Rick is back so he may chime in.

So it looks like Rick was correct! Bad file!
Might want to check your backup to make sure you don't repeat the problem in the future.

I also posted there.
Didn't fix the problem.
Still. I sent you a page with the problem pictured on a browser.

Sorry it's taking that long to solve it and tying up your time.

Well, it was fixed when I posted, but it's broke again and you're back to having some spaces in files. It looks like a couple were uploaded about the same time I was fixing things.

That was my bad.
I was uploading from the original 7.3.1 Install Pack.

Now the captcha is fixed. THANK YOU Rick!!!

still have a log-in problem that seams to be related with the same 'espaces' issue.

I'm still looking for spaces on my files.
